通过自组装[Cu-2(COO)(4)]桨轮SBU和一种新型的具有连接酰胺基团的三角杂功能配体,设计了一种具有kgm柱撑结构的微孔酰胺功能化金属有机骨架[Cu(NAIP(2-))]n. [Cu(NAIP(2-))] n表现出1060 m2 g(-1)的中等BET表面积、高CO2吸收(在0.15 bar和298 K下为4.5 wt%;在20 bar和298 K下为201.8 cm(3)g(-1))和在273 K下对CO2的高选择性(相对于CH 4(8.34)和N-2(38.3))。
A microporous acylamide-functionalized metal-organic framework with a kgm-pillared structure, [Cu(NAIP(2-))]n, has been designed by self-assembling [Cu-2(COO)(4)] paddlewheel SBUs and a novel trigonal heterofunctional ligand with a linking acylamide group. [Cu( NAIP(2-))] n exhibits a moderate BET surface area of 1060 m(2) g(-1), high CO2 uptake (4.5 wt% at 0.15 bar and 298 K; 201.8 cm(3) g(-1) at 20 bar and 298 K) and high selectivity for CO2 over CH4 (8.34) and N-2 (38.3) at 273 K.
